word sets- Convection takes place in liquids that are hotter at the bottom than at the top.
- A single deep connection to the magma supply maintains the heat input by convection.
- As for ordinary convection, this is what drives the motion.
- Figure 22.5 illustrates this, choosing the case in which the previous stage had produced bimodal convection.
- For very dilute concentrations, the convection distributed the particles uniformly throughout the tank.
- Hence, concentration driven convection occurs in these layers.
- In either case, the new flow, once established, is a new pattern of steady convection.
- This process is much simpler and quicker than cleaning a convection oven.
- This would not be possible if convection was taking place.

COLLOCATIONS FROM THE CORPUSNOUN► current
the movement in a gas or liquid caused by warm gas or liquid rising, and cold gas or liquid sinking· This keeps the solution flowing smoothly and, together with keeping the solution at 2°C, stops convection currents building up.· This is how a convection current works.
► oven· This process is much simpler and quicker than cleaning a convection oven.· Roasting in a convection oven, which circulates hot air over the surface of the food, works beautifully.· Care should be exercised with convection ovens to prevent solution ingress to the motor.· It can be used as a forced air convection oven alone - forced air being faster than conventional static hot air.
